DAI Haixia, SONG Weimin 127 da qi pm2.5 de jian kang ying xiang in: FOREIGN MEDICAL SCIENCES(SECTION HYGIENE), Year 2001 , Issue 5 , Page 299-303 http://caod.oriprobe.com/articles/3819302/127__da_qi_pm2_5_de_jian_kang_ying_xiang_.htmObviously, this scientific article is in Chinese. An abstract in English or Chinese is not accessible. Therefore most people outside China can not understand the graphic shown for the global situation above. The graphic above relates to this scientific article without specifying the value of the diverse colors used within the graphic to qualify different areas on the globe with different air pollution problems. Therefore this graphic is totally non-transparent and unable to explain to an outsider why one ought to use masks in China. One may only suspect that the air pollution in China must be bad because of the advertisement for air pollution masks. But it is not understandable. For sure, it may be understandable for Chinese as they see the smog everyday, it is not for a foreigner - unfortunately.
